Bridger Range, 2018-12-08

A skier in the Northern Bridgers found variable conditions on Saturday, with wind scouring above treeline, isolated wind slabs below treeline, and widespread faceting with the recent cold and dry weather. "Skiing was highly variable, ranging from all loose facets to breakable wind slab overlying facets to hard slab/sastrugi." Photo: G. Antonioli
